Performs an atomic addition operation on the specified LONG64 values.
Syntax
LONG64 _InlineInterlockedAdd64(
[in, out] LONG64 volatile *Addend,
[in] LONG64 Value
);
Parameters
[in, out] Addend
A pointer to the first operand. This value will be replaced with the result of the operation.
[in] Value
The second operand.
Return value
The function returns the result of the operation.
Remarks
The interlocked functions provide a simple mechanism for synchronizing access to a variable that is shared by multiple threads. This function is atomic with respect to calls to other interlocked functions.
This function is implemented using a compiler intrinsic where possible. For more information, see the WinBase.h header file and _InterlockedAdd64.
This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
Note This function is supported on Windows RT-based systems.
